IMPROVEMENT IN CHANGEABLE FEED-GEARS FOR FEED-CUTTERS.

Specification forming part of Letters Patent No. 164,222, dated June 8, 1875; application filed April 10, 1875.

To all whom it may concern:

Be it known that I, ROMANN SEELIG, of Chicago, in the county of Cook and State of Illinois, have invented an Improvement in Changeable Feed Gear for Feed Cutters, of which the following is a specification The object of my invention is to so construct the feed-gears and pinions of a feed-cutter as that, by reversing the two pinions on their shaft, (both being on a sleeve,) two changes of speed can be secured for the feed-rolls.

The invention consists in the combination of two {pinions of different diameters, mounted on a sleeve that is reversibly feathered on the cutter-shaft, with a wheel on the feed-shaft, carrying spur-gears of two different diameters.

Figure 1 is a perspective view of a feed-cutter embodying my improvements. Fig. 2 is a cross-section of the pinion-shaft feathered on the cutter-shaft. Figs. 3 and 4, respectively, show in elevation the pinions matched with slow and fast feed-gears. Fig.5isalongitudinal section through the pinion-sleeve.

In the drawing, A represents the frame'of a feed-cutter, across which is journaled the shaft B, carrying the cutters, and a shaft, C, carrying the lower feed-roll. D is a wheel mounted on one end of the shaft C, its periphery being a spur-gear of two different diameters, a b. E is a sleeve feathered on the shaft B, so as to be reversible by removing the crank F. This sleevehas cast 011 its end; two pinion .L small one, a, and a larger one, I).

Slipped on the shaft one way the gears a a will match, and communicate a slow motion to the feed-roll shaft C. The sleeve being reversed, the gears 12 b will match, and drive the feed-roll shaft more rapidly, thus enabling the feed to be adjusted for cutting the feed coarse or fine, as may be desired.

What I claim as my invention, and desire to secure by Letters Patent, is-

' The reversible sleeve E and its pinions a b,

in combination with the gear-wheel D, having gears a b of difierent diameters, substantially as and for the purpose set forth.
